RAILWAY-FROG.

SPECIFICATION forming part of Letters Patent No. 349,978, dated September 28, 1886.

Application tiled January 4, 1886. Serial No. 187,618. (Noinodel.)

To all whom it may concern:

Be it known that 1', JAMES J. BILLINGSLEY, a citizen of the United States, residing at Minden, in the parish of Vebster and State ot' Louisiana, have invented certain new and use ful Improvements in Railway-Frogs, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to railway-frogs; and it consists in the parts which will be hereinafter described, and pointed ont in the claim.

In another application for Letters Patent of the United States I describe, illustrate, and claim a double ilanged locomotive and car wheel.

It is the object of this invention to provide a frog that will bc suited to the wheel therein shown.

In the aecompanyi ng drawings,formingpart of this application, Figure l represents a plan View of a portion ot' the main track and switch with my frog at the intersection ot' the rails. Fig. 2 is a perspective view of the central block forming the main feature of my invention, and Fig. 3 is a plan view ofthe same.

Like letters indicate like parts in the several views.

A A represent the main-line rails, and B the cross'ties on which they rest. The inner :main rail,A,lying nearest the sidetrack, is cnt away between the points where one ot the side-track rails @intersects it. Said side-track rail C is also cut away at the point where it intersects the lnaintrack rail A. The cutaway ends of the intersecting rails are beveled from side to side. rI he degree to which the ends are beveled depends on the angle of inclination of the side track at the point of intersection with themain line.

C indicates the outside side-track rail.

D represents the block proper, which is interposed between the ends of the intersecting rails A and C. The sides of this block are vertical, so as to admit of the free passage of either a single or a double flanged wheel. lVheels of either construction may pass freely along the main line, or may be admitted to the side track, as may be desired. rllhe block D is provided with bottoni side langes, D',

.having openings Dl therein for the reception ot' spikes for securing the same to the crossties or underlying plate or block, as may be desired. These tlanges, if desired, may eX- tend from all sides ofthe block.

Il represents a plate resting upon the crossties under the frog. The plate is secured to the ties, and the frog is secured to the plate.

F F representguard-rails.

My frog may be also employed at a point where one railroad crosses another at right angles. ln that case the ends ot' the rails at the point ct' intersection would be cnt ott' square, and the intervening block would also have a square i'ace.

Having thus described my inveiniioinIclaim as new and desire to secure by Letters Patent ofthe United States- A railway-frog consisting of a qnadrilateral block with vertical sides, provided with bottom side ilanges, D, having openings 1); therein for the reception ot' spikes for securing the same to the cross ties or underlying plate or block, substantially as specified.

In testimony whereotI l al'lix my signature in presence ot' two witnesses.

JAMES J. BILLINGSLEY.
